Conserved charges and asymptotic symmetries of BTZ-like black holes in Einstein-bumblebee gravity
European Physical Journal C: Particles and FieldsUsing the solution phase space method, we investigate the conserved charges of BTZ-like black holes in Einstein-bumblebee gravity. Our study shows that the black hole mass, angular momentum and entropy are influenced by the Lorentz-violating parameter ...

Strings, Virasoro sandwiches and worldsheet horizons
Physics Letters BWe revisit the canonical quantization of free bosonic closed string theory and observe that the physicality of states requires vanishing of the worldsheet Virasoro algebra generators sandwiched between any two physical states.

Classification of simple Harish-Chandra modules over Q-Virasoro algebra
, 2007 We give a complete classification of simple Harish-Chandra modules over Q - Virasoro algebra. 1 Introduction A classification of the simple Harish-Chandra modules over complex Virasoro algebra V was given by O.Mathieu in remarkable paper [7]. According

The Virasoro vertex algebra and factorization algebras on Riemann surfaces [PDF]
, 2017 This paper focuses on the connection of holomorphic two-dimensional factorization algebras and vertex algebras which has been made precise in the forthcoming book of Costello-Gwilliam.

A Class of Representations over the Virasoro Algebra [PDF]
, 1997 In3and4, the indecomposable and irreducible Harish-Chandra modules over the Virasoro algebra are studied and classified. In this paper, we construct a class of indecomposable modules with infinite dimensional weight spaces over the Virasoro algebra.

Generalizations of Virasoro group and Virasoro algebra through extensions by modules of tensor-densities on S1 [PDF]
, 1998 We classify non-trivial (non-central) extensions of the group Diff+(S1) of all diffeomorphisms of the circle preserving its orientation and of the Lie algebra Vect(S1) of vector fields on S1, by the modules of tensor-densities on S1. The result is: 4 non-

Chiral Virasoro algebra from a single wavefunction [PDF]
Chiral edges of 2+1D systems can have very robust emergent conformal symmetry. When the edge is purely chiral, the Hilbert space of low-energy edge excitations can form a representation of a single Virasoro algebra.

Double-soft graviton amplitudes and the extended BMS charge algebra
Journal of High Energy Physics, 2019 We discuss how scattering amplitudes in 4d Minkowski spacetime which involve multiple soft gravitons realize the algebra of BMS charges on the null boundary. In particular, we show how the commutator of two such charges is realized by the antisymmetrized

Correlators of the symmetric product orbifold
Journal of High Energy Physics, 2020 We exploit null vectors of the fractional Virasoro algebra of the symmetric product orbifold to compute correlation functions of twist fields in the large N limit.
